Abstract
A photo-acoustic polarimetric remote sensing apparatus includes a telescope that directs visible light photons from an object. A polarizing beam splitter is in optical alignment with the telescope. The polarizing beam splitter has first and second pathways corresponding to first and second polarization states, respectively. The first and second pathways are substantially perpendicular. A first photodetector is in optical alignment with the first pathway, and a second photodetector is in optical alignment with the second pathway. At least one processor is in communication with the first and second photodetectors. The at least one processor generates a signal corresponding to a degree of linear polarization of the photons over time, and the signal is indicative of an acoustic signature of the object.
